Choosing between "renaming" and "copy"

I renamed a file in my repository, and made a slightly modified copy of it. It looks like GIT gets confused on which one is the renaming and which one is the copy, and doesn't favour the 100% identical one to be chosen as the renaming.

Not a big deal, but maybe git could be more clever here.
